"All of our premium red wines are vegan suitable.
We are looking into different finings for the Devils Creek Merlot but it might take a while."

Company email (February 2014):

"We have tried a number of alternatives however it seems this is required to achieve the softness in the wine for which it is so popular.
Many of our premium red wines are vegan suitable, notably the 2012 Teroldego which was recently awarded a gold medal at the 2013 Australian Alternative Variety Wine Show in Mildura last November."
